TRUNK-CHAIN.

Application filed. June 29,

To all 10 [mm may concern Be it known that I, CHAnLEs K. M rr- THEWS, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Trunk-Chain, of which the following is a specification.

My invention relates to improvements in trunk chains, in which a net work of chains is slipped loosely over a trunk and then tightened by gathering the chain ends which converge at one end of the trunk on a single chain loop.

The objects of my invention are to produce a trunk reinforcement for shipping purposes which can be attached with very little effort, is simple to manipulate, does not occupy much storage room, and will last indefinitely.

I attain these objects with the mechanism illustrated in the accompanying drawing, in which Figure I is a perspective view of a trunk with the chain in place.

F II is an end view of the same trunk showing the chain which forms the loop disengaged.

Fig. 111 shows a special link and the snap hook which engages said link.

Similar numerals refer to similar parts throughout the several views.

The trunk 1 is surrounded on all of its six sides by a net work of chains 2 whose crossing points are inseparably connected by rings 3, except on top and at one end where the rings are replaced by the snap hooks l. Before final tightening takes place these hooks can be put on the chain very easily and shifted to a bearing in the special links 5.

At one end of the trunk each converging chain has a loose end 6 with a ring at the extreme end. All these ends 6 are gathered on the tightening chain 7, and after said chain has completed the circle and hooked in at the point of beginning, suf icient tension has been produced in all the chains to make involuntary disengagement impossible.

In removing the net work the reverse process takes place. First the tightening chain is unfastened, and then the snap hooks at the end and on top of the trunk are unhooked, whereupon the net work can be thrown back as a coat may be removed from the body of a person.

Having thus described my invention it will Specification of Letters Patent.

be seen that my objects have been accomplished, and, though I have shown the preferred form of construction, I reserve to myself the right to make minor changes, providing I do not contravene the spirit and principle of my invention.

I claim:

1. In a trunk chain, the combination of a plurality of chains having rings at their terminals, said chains beginning at one end of the trunk, encircling the trunk in vertical and horizontal directions at right angles to the edges of said trunk and returning to within a short distance of the starting point, a short chain end secured in one of said rings, having a snap hook at the other end, adapted to slip through the rings of the free chain ends and hook in at the point of beginning.

2. In a trunk chain, the combination of a plurality of chains, two of said chains encircling the trunk in horizontal and in vertical directions at the one-third points of the respective edges, two of said chains encircling the trunk in horizontal and vertical directions at the two-third points of the respective edges, all chains beginning at one end of the trunk and returning to within a short distance of the point of beginning, a short chain end attached to one of the rings, gathering the rings of the free chain ends and returning to the point of beginning, and a double row of chains encircling the trunk at right angles to the longitudinal strands at the one-third and two-third points respectively and interlocking with said 1011- gitudinal strands.

3. In a trunk chain, the combination of a plurality of chains having rings at their terminals, said chains beginning at one end, encircling the trunk in pairs in horizontal and in vertical directions, and returning to within a short distance of their starting points, a short chain end gathering the rings of the free chain ends, and a double row of chains encircling the trunk at right angles to the longitudinal strands and interlocking with said longitudinal strands at their crossing points, the sections at the top and at one end between the longitudinal strands having snap hooks adapted to seat in curved links in the longitudinal strands.

Signed by me at Portland, Oregon this 23rd day of June, 1920.
